Reaction Steps
A mixture of 10.7 g. of 6-(p-fluorophenyl)-1,2-dihydro-2-oxonicotinonitrile [J. Med. Chem. 14, 342 (1971)] and 16.8 g. of 4-piperidinopiperidine in 140 ml. of dimethyl sulfoxide is stirred and heated at 95°-100° for 50 hours. The mixture is cooled and diluted with 450 ml. of 95% ethanol. The resulting precipitate of 6-[p-(4-piperidinopiperidino)phenyl]-1,2-dihydro-2-oxonicotinonitrile is collected by filtration, washed with 95% ethanol and dried; m.p. 288°-293° (dec.).
